Cadillac 2004 DeVille - Manual (Page 146)

Twilight Sentinel ®
This lever is located next
to the exterior lamp
control. It automatically
turns the lamps on and off
by sensing how dark it
is outside.
To operate the Twilight Sentinel ® , leave the exterior
lamp control in the off position and move the TWILIGHT
lever to any position but OFF.
If you move the lever all the way to the right, the lamps
will remain on for approximately three minutes after
the ignition has been turned to OFF. If you move
the lever so it is barely on, the lamps will go off quickly
when you turn the ignition switch out of OFF. You
can adjust the delay time from only a few seconds to
about three minutes.
If it is dark enough outside and the Twilight
Sentinel
® lever is off, a HEADLAMPS SUGGESTED
message will display on the Driver Information Center
(DIC). This message informs the driver that turning
on the exterior lamps is recommended (it is become
dark enough outside to require the headlamps and/or
other exterior lamps). Turning on the Twilight
Sentinel
® or turning the exterior lamp control to the
headlamp position will remove the HEADLAMPS
SUGGESTED message.
